Camera Raw updates Date Taken in JPG Files

Tags: #photoshop #camera_raw #cs6 #date_taken



I have CS6/CR 7.2.  I have had this issue where my file dates became changed (8000 odd files) so I had to restore 23000 files from backup


When investigating trying to find out what happened.  when I open a JPG from Windows Explorer, photoshop is set to use Camera Raw for jpg files on open (ok).  If I cancel the dialog, nothing happens (ok).  If I click Done or Open Image, the file itself has the "Date Taken" time updated - 7 hours ahead of the original correct time. 


This pretty much matches the date issue I have on the 8000 files.  Is this expected behaviour?  Why would Camera Raw update Date Taken and did it choose 8 hours because I am in the PST timezone (GMT-8 or currently GMT-7 with daylight savings)?


I have reproduced this on 4 or file random files - taking copies and comparing afterwards.

    Camera Raw writes your JPEG files back out with updated metadata no matter what settings you choose, because Adobe feels they understand the format of metadata in the files well enough to be confident they will not corrupt the files.


    I've asked them for years to avoid doing that, to no avail.  I don't want my original files re-written.  It sounds as though you are of a like mind. 


    It is for this reason that I *never* open a JPEG file through Camera Raw.


    It's possible there is a time zone problem or something, but that's not the point.  What, specifically, is corrupted is less important than Adobe believing it's okay to write back to your JPEG files.  That you have actually seen something corrupted is testament to it not being unfounded paranoia.


    Generally I'm supportive of Adobe's design decisions, but absolutely not on this issue.  All I ask is that Adobe honor the "keep settings in the central database" preference choice for ALL input files, not just those for which they would otherwise write an XMP file.  I don't think it's too much to ask.


    By the way, you might want to visit the Camera Raw-specific forum and make note of your issue there:

    How are you assessing this? (please send me a jpeg, with info: what the correct time should be, and what the (modified incorrectly) date-time is).


    If you also have a reference (un-malflicted) jpeg to send, it would help to compare.


    To be more specific: the question is: "is the exif:dateTimeOriginal tag being incorrectly re-written?" (it shouldn't be), or is the xmp:dateTimeOriginal tag being incorrectly written, and subsequently reported (my current theory).


    Plugin note: if my theory is wrong, and the problem is the former (exif-tag itself being re-written), then MetaRep won't be able to fix the problem, *and* it represents a bigger bug in my mind, since writing xmp is more Adobe's perogative than altering exif tags (given that they will be updating even camera-original jpegs, and don't support sidecars for them - a related yet different issue...).
